COVERED mirarme BODY.

Application led July 29, 1925.

rihis invention relates to vehicle bodies ot the hopper type in which the body is mount ed for tilting by rolling upon a main frame oi the vehicle for the purpose oi' dumping,` its contents. The object of the invention is to provide covering,` means for such a body, adapted to be opened at Will, and so mounted as not to alter the center ot gravity of the tilting body, or interfere with the dumping motion, it consists in certain 'features and elements of construction in combination as herein described and shown in the drawings and as indicated by the clain In the drawings:

Figure 1 is a side elevation ot a trailer type of vehicle carrying,v a hopper body fitted with covers embodyingthis invention;

Figure 2 is an end elevation ot the body and its support, but with the adjacent Wheels and running` gear removed for showing the body more clearly.

F'O'ure 3 is a vertical detail section taken substantially at the medial plane of the vehicle at one end for showing the body-locking;` mechanism and the relation ot the covers thereto.

Figure i, is a partial end elevation showing;- a modiiied torni oli cover-litting,r mechanism.

in the constructimi illustrated the trailer comprises a drop iframe, 1, which is supported on tour wheels, preferably steering' wheels having suitable connections with draw-bars, El, for control ofthe steerin mechanism when they are attached to a tractor vehicle or pulled by a team of horses hitched to a tongue inserted in the coupling,` head, 4t, of the drawbar. Suitable locking),` mechanism, not shown, is provided for preventing steering,1 movement oi the rear pair of Wheels when desired. The load-carrying body is in the form of an upwardly open hopper, 5,1itted with rockers, 6, of channel section, Which are mounted to roll laterally upon cross rails, 7, carried by the drop trame so as to facilitate discharge of the loadv from the body when it is rolled over on its side to the position imlieated at in dotted outline in Figure 2. The center of gravity ot' the hopper body, 5, is so located with respect to the rockers, 6, that the body may be readily returned to upright loadreceiving` position by hand. Therefore, it is desirable in providing any formi of cover,

that the cover shall not beA attached to the body, since that would tend to shift the cen- Seria No. 46,730.

ter of gravity laterally in tilted position of' the body and render it ditlicult to return the body by hand from its dumping position to uprightposition.

As shown in the drawings, an A-frame of angle members 8, 8, is erected at each end of the body upon the end portion, 10, of the main frame, and ar longitudinal member, 9, preferably in theform of a pipe, is supported by the A-rames over the center line of the body. For convenience the covers, 11, are made in four parts, two at each side of the pipe, 9, and hinged thereto for swinging,- upwardly to a position shown in dotted lines at 11a on Figure 2, to permit loading the hopper body, 5. Each cover is fitted at its upper edge with eyes or rings, 12, encircling the pipe, 9, and serving as hinge members, and each cover may be provided at its outer end with a skirt or flange, 13, preferably depending' slightly below the level ot' the upper edge of the hopper body, 5, and overlapping the latter.

, For lifting the covers to loading position the A-frame at each end of the body supports laterally-extended arms, 14, carrying pulleys, 15, over each of which passes a cable, 16, anehored at 17 to the cover skirt or flange, 13. T he opposite end of the cable is attached 'to a winding,v drum, 18, toward which it is guided over a pulley, 19, pivoted on one of the members S. A hand crank, 20, is provided for operating the Winding drum, 18, While a pawl, 21, and ratchet Wheel 22 on the shaft ot the drum, 18, serve for holding the cable, 16, at any position of adjustment, such as that required for supporting` the cover at the elevated posit-ion indicated at 11a in Figure 2. ln this position the cover is raised quite clear of the body so as to permit loading,` the latter or rolling it over to the dumping position indicated at 5a. Preferably the contour of the covers is such that the side of the body which rises in the rolling movement describes a path which lies entirely under one of the covers, and, o1 course, passes under t-he fixed trame member, 9. This renders it only necessary to raise the covers at that side of the body at which the load is to be dumped.

Since the covers are preferably made of rather thin material, and since the lifting cables, 16, are attached only at one end of each cover, there is some tendency for the Weight ot the material to cause warping or twist-ing' oi the cover as it is lifted, unless some auxiliary Stiliening means is provided, For this purlll.)

Cit

pose truss members, 23, in the form ot rods or cables, are stretched diagonally over each cover from the anchoring brackets, 2% and 25, attached near opposite corners ot the covcr, and With a strut bracket, 26., aft about the middle ot the cover and preferably secured to the reinforcing strap, 27, which terms a part ol one of the hinges, 12. Thus the lifting stress is transmitted trom `the flanged end of the cover to the opposite end without unduly distort-in the cover itself.

To keep the construction as compact as possible l. preterto mount the, driving seats, 30, so that they may be folded up close against the iti-trames, 8, and likewise the toot-boariils, 32, are hinged at 323 for folding back Within the length ot the main trame, While chains, 3l, are arranged to support them when in eze tended posit-ion, as shown in Figure l. Yiihere the covers ll are specially heavy, the ivorl( olf raising them may be made somewhat easier by ext ding the arm, lil, slightly farther, as shown at lla in Figure l, and anchoring the cable, 16a, aY the cxtreme nd ot the arm, l-lfl. This lable is thon led around a pulley, 1T, on the end flange, 13, ot the cover, ll, and thence around the pulley, l, on the arm, le, thus reducin by one-lralt the ei'iort required to operate the Winding crank, 20.
